Thanks. Do you think it will i perform smother with closer tolerance? Some seems to think so, but I've not been able to find any examples. I bought this pedal after realizing that all of the MPX versions needed some tweeks to make them perform at they're best. If I need to do mod anyway, why not do it on this cheep version

I've noticed one thing. Look at the two diodes at the power inlet. They're raised up from the PCB board. There are a couple of resistor that are mounted the same way. Is this doe to sloppy mounting, or are they mounted that way on purpose to hook up metering?

Quite sone years ago I had a fried Boss phaser staying over. Among other things even the FET's were very dead. Takes quite some effort to achieve that.

Anyway, that was my first adventure into FET matching and therefoer I breadboarded a quuick FET matcher setup.

First FET in: Reading.Next: Same readingnext: some mV differentNext, initial reading againThis went on for quite some FET's and I started to doubt my FET matcher. So I took te junk bin and started testing random FET's. All different readings. Back to the originally tested ones which all measured exactly the same again. What the originals did have in common though is that they all came from the same batch/production run.

Which made me conclude that apparently these manufacturers have their process in control so tightly that spec-deviations in a batch are minimal. Therefore I highly doubt that soldering matched FET's in this Joyo will offer any improvement since what's in it is matched already. Therefore save yourself the energy.

I got the Harley Benton Vinage Phase (Joyo JC-06) and I was trying to do the R28 mod to get rid of the distortion this pedal produces while engaged.Could't find the resistor (24k) on the PCB and maybe someone alread did the mod to his pedal.
